Lewis dot, electronic and molecular geometry

Click For Summary
SUMMARY

This discussion focuses on determining the Lewis structures, electronic geometries, molecular geometries, and polarities of the compounds NO2Cl and SOCl2. For NO2Cl, the Lewis structure indicates a total of 25 valence electrons, leading to a trigonal planar electronic geometry and a polar nature. For SOCl2, with 26 valence electrons, the Lewis structure suggests a trigonal pyramidal molecular geometry, which is non-polar. The participants seek clarification on how to accurately determine electronic geometries.

PREREQUISITES
  • Understanding of Lewis dot structures
  • Knowledge of valence electrons and their distribution
  • Familiarity with molecular geometry concepts
  • Basic principles of molecular polarity
NEXT STEPS
  • Study the VSEPR theory for predicting molecular shapes
  • Learn how to calculate and interpret molecular polarity
  • Explore advanced Lewis structure drawing techniques
  • Investigate the relationship between electronic and molecular geometries
USEFUL FOR

Chemistry students, educators, and professionals involved in molecular modeling and analysis, particularly those focusing on molecular geometry and polarity assessments.

Draw the lewis dot, identify the electronic and molecular geometry and determine the polarity of a) NO2Cl and b) SOCl2

a) N has 6 valence electrons
O has 6(2) = 12 valence electrons
Cl has 7 valence electrons
Total : 25

For the Lewis Structure: (* is for space)

O-N-O
**|
**Cl
I distributed 6 dots around the 2 O's and Cl but N has one valence electron on top and it is unevenly distributed.

I think the electronic geometry is trigonal planar and it's polar.
I'm not sure about the molecular geometry.
---------------------------------------------------------------------------
b) S has 6 valence electrons
O has 6 valence electrons
Cl has 7(2) = 14 valence electrons
Total: 26

For the Lewis Structure: (* is for space)

**O
**||
Cl-S-Cl
I distributed 6 valence electrons around the 2 Cl and 4 dots around O making a double bond between O and S.

I think the molecular geometry is trigonal pyramidal and it's non polar.
I'm not sure about the electronic geometry.

Please help.

Well how is the electronic geometry determined?
